comment Cutesy Applications of Fermat's Last Theorem (or others)
From the other part of the product $(a^n-b^n)^2+(b^n+c^n)^2+(a^n+c^n)^2 = 0$.

comment Cutesy Applications of Fermat's Last Theorem (or others)
One of the factors given by the equation is $a^n+b^n-c^n$ which by FLT is never zero.

comment Proving that a Finite Field Over Its Prime Field Is Galois
I don't remember making this review. Galois theory is not among my favorite subjects neither... Maybe your answer got mixed up with something because it is too short, like a comment.

comment Minimizing $\int_{0}^{1} (1+x^2)f(x)^2 dx$ for $f(f(x)) = x^2$
@mick: No one's voting to close because a source is missing, but the fact that you are the source and you don't know the solution is not very encouraging. I asked since some problems taken from high profile contests or exercices from advanced books are not easily solved if you don't have some context. Furthermore, if you just made up the problem, it may not even be possible to solve it...

comment Minimizing $\int_{0}^{1} (1+x^2)f(x)^2 dx$ for $f(f(x)) = x^2$
What's the source of this problem?

comment Minimizing $\int_{0}^{1} (1+x^2)f(x)^2 dx$ for $f(f(x)) = x^2$
@AlfredYerger: I think $f^2$ means $f$ squared. If the superscript refers to composition like you say, then you just replace by $f\circ f$ by $x^2$ and you don't have anything to optimize.

comment How can you plot straight lines in Matlab using only values on x axis and the gradient of each line?
If you want any real help with your Matlab code you'd better write the whole code properly and then ask exactly what you need. You do not explain the mathematical problem and it is not really clear what you want the matlab program to do.
